To all whom it may concern:

Be it known that -I, F. F. RAYMOND, 2d, of Newton, in the county ofMiddlesex and State of Massachusetts, a citizen of the United States,have invented a new and useful Improvement in Heel-Nailing Machines, ofwhich the following is a full, clear, and exaet'description, referencebeing had to the accompanying draw: ings, forming a part of thisspecification, in explaining its nature, in whicht Figure 1 is a view,part in vertical section and partin elevation, of amachine containingthe features of my invention. Fig. 2 is aview, part in horizontalsection and part in rear ele- Fig. 3 is a view, part in end elevationand part in section, of the nail forniing and feeding deviceshereinafter described. Fig. l is an enlarged view, part in verticalsection and in perspective, of a portion of said device. Fig. 5is a planview below the line :0 a; of Fig.1. Fig. l is a plan view below theliney y oi 1; Fig. 7 is a vertical section illustrating the naildistributor or holder. Figs. 8 and l relate to the feeding mechanism forautomatically revolving the nail distributer and holder, as hereinafterspecified. Fi g. 10 is a detail view showing a portion of thenail-holder, its movable bottom plate, and a nail-carrier, andrepresents the method of operating the sliding bottom plate by thenailcarrier; Figs. 11, 12, and 13 refer especially to the devices forpointing the wire from which the nail is made, and which are hereinafterparticularly referred to. Fig. 14 represents in elevation the completenail.

'lhe invention relates to machines for attaching heels or heel-blanks toboots and shoes; and it comprises devices or mechanism for forming andcutting nails from a single wire, for sorting or distributing them, forfeeding them to a position to be driven by the drivers, for preparingthe heel for their reception, and for attaching the heel. i

In the drawings 1 have represented this mechanism as applied to aNational heel-nailing machine; but it may be used in connection withany-other heel-nailing machine;

- Referring to the drawings, A represents the reciprocating cross-headof a National mach'ne; a, the revolving head, which carries the gr up organg of awls a, the group or gang l l l 5 Patent No. 317,199, dnt ed May5,1885.

At allother times the holes are covered.

7 Thus far the machine does not varyfrom the one which has already beendescribed in the Henderson patents above referred to, and in variouspatents granted to me. To automatically feed the nail holder 1 havearranged above the table '0", which supports the templet and nail holderplates, a nail-holder, It, in such aposition that the nail-holderl) (orcarrier, as I now prefer to call it) sh; ll under the same by the cam d"and. lever d upon its backward movement into positi on to receive thenails which have previously been deposited-therein. ing plate or disk 0,the holes therein by backward movement,

As, however, it is necessaryto be stationary,or it may be movedinto to the nail be brought immediately This holder has the slidingclos-'- which is moved to uncover again immediately reload the holderafter it has deposited its nails into the carrier; I have sotimed theeamal that it moves the carrier after the reciprocation of the drivers aback to the position under the holder, where it mit the nails to dropfrom the holder therein,

to open the holes by the when it is moved forward a slight distance,sufficient to enable the closing-plate c to be shut automatically andclose the holes in the holder, so that it can be immediately refilled.The holes in the holder must correspond with the holes in the carrier.The plate e is moved contact of the pin e therewith on the backwardmovement of the carrier, and is closed by the spring 6 For feeding thewire forming the nails and position to be taken by the distributingdevice hereinafter described, I may use with proper modifications any ofthe well-known nail-forming machines of the market, and I have shown inthe drawings as applicable for this purpose a portion of a machine shownand described in Patents N 0s. 225,527 and 301,464, and have added to itonly such devices as can be easily added to any other of the well-knownmachines of the market for accomplishing the result desired.

0 is the reel for holding a coil of Wire.

e is the main shaftof the nail-forming mechanism. It operates thewire-feedihg rolls e 6, described in said patent, and has a driver, e,which is reciprocated as therein specified.

The blank cut from pointed, (see Fig. 14,) although a partiallyi'ormedstring-nailinay be used,if desired; but in the machine I have showndevices for form ing a flat tapering point on each blank, and the wireis fed by the feeding mechanism into a hole, f, in the block F, whichhas a reciprocating movement given it by means of the camf and leverfand it hasa V-shaped projection, f extending from itslower portion,through which the hole f extends, and which supports the lower end ofthe nail as it is advanced by the cutters f to a position to be ejectedby the driver 6. The cutters are inclined upon their cutting edge, andare arranged to sheara small section on abevel from each side of thenail as the nail is moved by them.

The reciprocating block advances the nail to a position under the driver6, and the driver drives the blank down through the driveway of themachine into the distributer G. The reciprocating block is to a certainextent like that described in my pending application filed April 14,1884, Serial No. 127,756, and it per-.

forms these offices, first, in connection with the throat-plate f, itsevers the nail-blank from the wire; second, it moves the nail-blank tothe cutters, and, third, it advances the nail to a position under thedriver, from whence it is driven by the reciprocation of. the driverinto the distributer.

The distributing device comprises a circular block, 9, in which aredrilled at uniform distances apart a number of holes, corresponding tothe number of the nails to be driven in attaching a heel. This disk orblock is automatically revolved by means of ratchet-wheel f, thespring-pawls the lewithout giving the Wire preferably is er 9, pivotedat g", and operated by a camgroovc, g", in the cam-cylinder g on themain shaft 0". I do not confine myself to this means of revolving thedisk or block, but may use any other equivalent means for so doing. Theholes in the block are so arranged as to come in line with the holes inthe nozzle or feedway of the machine, and the disk or block is revolvedthe distance between the two holes each reciprocation of the driver.This brings the holes successively in position under the driver toreceive the nail. The nails, how ever, nnast be carried automatically tothe nail-holder .E, and placed in their respective holes therein, and inorder to do this I connect the nail-holder with the disk or block 9 bymeans of a post, g, or in any other desirable way, so that it willrevolve therewith and connect the holes in the disk or block with theholes in the nail-holder by means of passages or tubes These tubes notonly connect the holes, but guide the nails, so that they are directedfrom the nozzle of the nail-supplying machine to their proper place inthe nailholder, and by using a circular feed-plate with holesuniformlyarranged therein. This is done any one tube a direction muchout of a vertical line. It will thus be seen that the nails are properlydistributed. This distributer comprising the nail-holder and the disk orblock I have represented as being supported by the plate H and thebracket H,- but any other suitable support therefor may be used; and inFig. 2 I show the plate H extending across from. one side of the machineto the other, and broken out at its center to show the mannerofsupporting the nail-holder, and in the same figure I show the bracketH in vertical sect-ion and the upper part of the distributer restingthereon: These two plates and therelation which they bear to thedistributer as a whole are also shown in vertical section at right angleto these views in Fig. 1, and the office of these plates is to properlysupport the nail-distributer and furnish upper and lower bearingstherefor, which permit its revolution therein.

In order that the machine may have sufficient time to form anddistribute the nails necessary for loading the nail-carrier, I havearranged mechanism for automatically starting the machine immcdiatel yafter the nail-carrier has received its load of nails from. thenailholder and started forward a short distance. as above'spetinm, sothat the time utilised in spanking the top-lift, if a spanker is used,and the time which is employed by the operator in removing his work fromthe jack and in placing new work thereon and in locating it in properposition may be used for forming, feeding, and distributing the nails.In order to accomplish this, it is of course evident that the shaft ecannot be connected with any shaft of the heel-attaching machine whichstops, and it must therefore either be connected with the pulleyshaft,if the pulley-shaft is run continuously,

or with an independent shaftor counter-shaft which is run continuously.To such shaft the pulley-clutch M is belted. This pulley-clutch ismovable on the shaft e and engages the section m, which is splined tothe shaft. The positively-driven member of the clutch is movedintoposition and held there by means of the spring in and lever m, which ispivoted at m and connected with a hub or sleeve, in, attached to thepulley M, and I move it out of position automatically after any givennumber of nails have been vTori-nod and driven by means of the arm orlever m, which is pivoted at in to the lever m, and which extendshorizontally, so that a projection, m upon the revolving disk or block Eshall on each revolution thereof come in contact with its end and pushit horizontally sufficiently to move the portion- M of the clutch fromthe part in, and at the same time cause the frictiondisk of, which isattached to the'lever of, to

come in contact with a friction-disk, in, which is rigidly attached tothe shaft 0", so that the nail feeding and fori'ning devices areimmediately stopped. preferably, in plan as shown in Fig. 6, the outersurface being of such shape that a pori-lOII GXiZGDGS behind "the end ofthe rod in before it comes in contact therewith to push it outward.

To start the machine at the time above indicated, I use the cam N on theshaft or and'the connecting-rod n. This cam is so shaped that at theproper linie it lifts the rod n, which,-

being connected with the lover of, lifts it and holds it lil'led untilthe projection m has been moved by the revolution of the block or disk1*] suiliciently to permit the spring m to move the clutch M intoengagement, and also the lever in forward, to be again moved back by theprojection m after it has made a full rcvolution, as above indicated. Ido not, however, confine myself to the specific stop-motion mechanismherein described, but may use any mechanical equivalent therefor.

To provide for the feeding of a greater or less number-of nails, thedistributor, oompris ing the disk or block, the nail-holder, and itsconnection, is removed and'another having a greater or less number, asthe case may be, substituted, inwhich case the stroke of the pawl willbe adjusted to make a longer or shorter throw, anal prefer to make theblocks or disks of the sa'me'size,'in which event-,when, more nails areto be used, the holes will be nearer together, and of course the feedwould .be the only thing that would have to be adjusted in making achange from one size to another. Of .course each hole in the disk orblock is connected with a corresponding hole in the holder.

In using a nail having a point formed by two bevel-surfaces it.-will bedesirable for certaiukinds'ot' work not to use the a\vls, usithe nailsthus pointed can be driven by the drivers without first punching ilOILSin the heelblank.

holder.

The projection mi is shaped,

with nails from the nail-holder, is then moved forward and deposits itsnails in the templet-Z The cross-head is again reciprocated, driving thenails into the heel-blank and heel end of the boot or shoe soles. Thecarrier is withdrawn, either immediately after the nails are depositedor immediately after the reciprocation of the drivers, to a position toreceive from the nailholder the next charge or load of nails, and isthen immediately moved for-- ward a short distance, and the disk orplate automatically closing the holes in the nail- At that instant thenail forming and feeding mechanism is automatically set in motiou, andthe nails are successively out off and distributed, and its actioncontinues until it has cut off and distributed enough nails to load thenail holder, when it is automatically stopped, and remains inoperativeuntil the nail-holder discharges its nails into the nailcarrier, when itis again set in operation, as before. f

lt'will readily be seen by this mechanism. suiiicient time is providedfor forming from a single'wire and distributing allthe nails which areneeded for attaching the heels, and that the nail holder and carrierarealwayscharged with nails in advance of the time of use. It will also.be seen thatthe efliciency of the machine is increased and thatconsiderable sav ing in-the cost of nailingis eifected, or less helpwill be required for running the machine. It will also be noticed thatthe mechanism, in whole or in part, can be used for loading heelblanksas well as for attaching heels, and also that the wire may be of anyshaped section desired, or may be a partly-formed or string nail, asabove stated.

It will be noticed that the nailmaking devices are set inoperation-immediately alter the nail-holder discharges its lead into thenail-carrier, and that they continue to operate in making the nails andin feeding them to the holder until the holder has again been filled,when it automatically stops. It will also be observed that the operationof the nail making and feeding devices after they have been start ed bythe heel-nailing devices is continuous, and that they do not stop on thecompletion of the heel-nailing, unless the holder has been iillcd withnails.
